Pedophiles got their due in two separate Manhattan prosecutions today, including a man who repeatedly abused an eight-year-old girl in Washington Heights and a male nanny who possessed child pornography.

Cesar Zuniga, 32, of Washington Heights, was sentenced to 15 years prison for sex abuses over a six-month period against the eight-year-old.

“This is a tough and appropriate sentence for someone who continuously preyed on a helpless victim,” DA Cyrus Vance said, noting the girl’s courage in coming forward.

The nanny, Richard Figueroa, 23, meanwhile pleaded guilty to three counts of possessing child porn, and will serve at least three years in prison, Manhattan prosecutors said.

Figueroa remains under investigation for allegedly molesting a Morningside Heights toddler under his care for three years, while the boy was ages 2, 3 and 4.
